To all whom it may concern: 1

Be it knownthat I, LAni'sLAv MisURA, a, citizen of the United-States, and a resident- 1 of'Newai-k,in the county of Essex and State of Newkler'sey, haveinvented new and-useful Improvements in Detachable Shoe Heels,-

' of which the following is aspecification.

damaging the shoe.

One object of the invention is to provide a heel of the character described embodying;- novel and improved features ofconstruct'ion" whereby the heel 'inay be ;mor e-fsecurely:

fastened to a shoe and, more easily (11d quickly applied'to and "rem'ove dfrom a shoe' than has been possible. withlknown heelsv v depressiono stamped in thezupperside there- 1 of this type. 1

'Another objectislto provide such a heeli' including a metal plate :adapted to carry a heel lift or tread and embodying'novel and improved featuresof constructionfifor securing SZLlCl lift or tread thereto, and

means for detachably; fastening said plate,

' toa shoe. Y 7

I this character. including a metal plate having projections 1 on one side thereof and a rubber'lift 'or tread molded thereonaround; 1 said projections whereby said tread is'per- 'manently secured to :said plate, and means 3 tread carrying Further objects are to provide a heel of for detachably fastening said plate to a shoe; to provide in combination with "said plate i a second plate adapted,

- to be permanentlyfastened to'a..shoe,said

two plates embodying improvedufeaturesiof construction to enabletliem *tointerlocleagainst movement longitudinally and'laterally and preventrelative tilting. thereof, and

I Figure a locking member or key for holdingsaid:-

Referring to the accompanying drawings 1 in which the same reference characters designate corresponding and .like parts. I i J 1 v l T LThe straps v 11; and 12 in conjunction with the respective grooveso and 6 are adapted to which throughout the several views,

Specifically fdescribing. presentflem- .bod-iment L of the.invention, the reference .character elf designates a; sheet metal. plate provided with openingsfz; to receive screws,

of and a pair of-s'nialler longitudinal grooves Gonearranged at eaclrjside of'the central groove-,5. Afpairofwslots Tare formed in the plate 1 transversely of-the de- -pression 5, and similarislotsS are f'ormed I isalcomposite perspective view of theeparts of-th'elieel separatediand'de-j plateand withzthe. tread or in-thef depression'sfor grooves-(6 adjacent the" outer ends thereof. In this connection, it will be noted that the grooves-5 and 6 open throughfthe edge of the plate ,1, as clearly shown inFigures 2 and 5.

Atreador lift carryingplate 9 is adapted .to fit within the flange 4 of theplatel and togbeldetachably-secured to said plate. I he plate 9 is'also provided with a peripheral filange 110 at its; upper side-i adapted to fit -w-iitl'iin the flange 40f the plate 1 and abut the underside of, said, plate. 7 llwo straps 11 corresponding in position and'sizeto the openings 7 in the plate 1, are stampedfroni the plate 9 and project from the upper side thereof, said straps being adapted to project througli't-he opening 7 with their upper Sides lplatef9 and adapted to" project throughthe openings 8;

receive a :key or; looking member 13 is iesubstantially, T- shaped and" provided with a central =steni portion 14 adapted to fit the groove 5 and slip beneath the straps is ofiset laterally from the stem, as shownin Figure 5, to form a finger hold, and the a ends of said headare provided with arms 18 adapted to slip through the straps 12,; as shown in Figure 2. With the 'plates 1' 1 and 9 assembled and the key 13 in position, thewpla'tes are rigidly held-against lateral or transverse'relative movement by means of the engaging flanges 4 and "10 and the edges of the slots 7' and 8 engaging the edges oft he' straps 11 and:12,:and theplates are positively connected by the locking key '13 1 interposed between the straps 11 and 12 of 1 the plate 9 and the bottoms of the'grooves 5 and 6 in the top plate 1;: Thegrooves 5 V and 6'. are of such a depth as to cause the undersides thereof to bear against the'top si'de of'the plate 9 so that rocking, springing or relative tilting of the plates 1 and 9 is prevented. The grooves 5 and 6 also permit the straps 11 and 12 to pass through the slots 7 and 8 without interference or engage "ment thereof with the shoe; they-also permit use ofthe key 13 without countersinking -,or recessing the shoe and serve as guides for th-e-key'to enable easy manipulation thereof and 9.

While the heel tread or lift may be se cured to the plate 9 in any-desired manner,

where a rubber tread such as indicated at 19 is tobe used, I prefer to permanently connect the tread to the plate 9 by a: molding process so as to eliminate'fastening members and thereby simplify the attachment of thetread to the plate and obtain a more posi-' tive' and secure connection of the tread to the plate. In accordance with the invention, the plate 9 has stamped therefrom' a'plurality of loop-like projections 20 which ex 'tend from the underside of the plate 9 considerable distance, as shown in Figure 4.

7 These projections preferably include substantially circular central portions 21 having apertures 22 therein. The tread 19 is applied to the plate by molding the rubber around said projections 20, f the rubber passing through the spaces between the projections and the plane of the underside of the plate, as indicated at 23, andalso through the *"plate-9' formed by the-stamping outv of the till projections 20, as" shown in Figures fand the plate 9, andv in changing a heel tread all that'is necessary is to remove the key 13 which permits the tread 19 and plate 9 ,to fall away from the plate 1 by action of gravity, apply a new plate 9 carrying a new tread to thep-l'ate 1 and reinsert the key 13.

The plate9 being formed wholly'of sheet invention. w'lherefore, I'do not desire to be understood as" limitingmyselfexcept as required by the following claims when construedin the l-ightfof the prior art,
